MOTOR MOUNTING.

Application filed June 28,

To all whom it may concern:

Be it known that I, TIMAN H. FIELD, a citizen of the United States, and resident of Rice Lake, in the county of Barron and State of VVis consin, have invented a new and 1mproved Motor Mounting, of which the following is a full, clear, and exact description.

It is a well appreciated fact in connection with motor vehicles, that considerable difficulty has been experienced in transmitting the power developed by the motor to'the rear axle. More particularly this difiiculty is to be predicated to the universal joints.

Primarily these conventional elements have required attention at regular intervals in that it was necessary to lubricate the same and to tighten the parts. Due to the somewhat inaccessible location of the same this treatment has been neglected by the usual operator resulting in the parts becoming noisy and worn and necessitating a complete renewal of the same.

The second difliculty is to be found in that due to the fact that the power is not transmitted in a straight line, a considerable amount of the driving power is not transmitted to the rear axle.

With these and further defects in mind my present invention aims to provide a form of motor mountin which will eliminate the difficulties heretofore experienced in that primarily the universal joints will be eliminated so that the attention heretofore necessary to these parts may be dispensed with, and secondly my invention is of such a character that the full power derived by the motor will be transmitted to the rear axle.

Reference is had to the attached sheet of drawings as illustrating one practical embodiment of my invention, and in these drawings it will be noted that;

Figure l is a plan view of a motor chassls illustrating the conventional part diagrammatically, and

Figure 2 is an enlarged sectional side View taken along the line 2-2 and in the direction of the arrows indicated in Figure 1.

The essence of my invention consists in mounting the motor in such a manner that the same is capable of moving to a limited extent and in direct proportion to the move ment of the rear axle incident to the wheels of the latter passing over irregularities in the road and the weight carried by the varied.

Thus a direct drive (with the exception 1921. Serial No. 480,957.

of a conventional clutch, gear transmission etc.) may be accomplished. This is to be attributed to the fact that the crank shaft of the motor may extend in the form of a propeller shaft and the end of the propeller shaft will align with the proper portion of the rear axle.

Thus in the drawings the reference numeral 5 indicates the frame of the chassis which is mounted upon a front axle 6, and is also provided with a rear axle 7 of any desirable type in accordance with the conventional construction.

Contrary to the conventional construction however it will be seen that the side members of the chassis frame preferably have brackets 8 secured to them. Further at a point spaced from each of the brackets, a bearing member including a pair of parts 9 and 10 is positioned. It is to be noted that the bearing part 9 is fixedly attached to the chassis frame while the bearing part 10 is formed with a longitudinally extending groove 11 through which a pin 12 secured to the chassis frame extends. Thus this latter part of the bearing is capable of movement with respect to the chassis and it is to be noted that the same is normally projected towards the bearing part 9 by means of a spring 13 interposed between the end of the bearing part 10 and the bracket 8.

Further the motor 14 has brackets 15 secured to its side walls, and headed'trunnions 16 form continuations of each of the brackets 15, these portions being embraced by the recessed ends of the bearing part 9 and 10, which latter are pressed into intimate engagement by virtue of the spring 13, thus preventing an accidental detachment of the motor from the support formed by these bearings.

-Assuming now that the rear axle 7 moves due to inequalities in the road, or incident to the chassis receiving a load, it will be appreciated that the movement of this member with respect to the chassis will immediately be imparted to the rigid propeller shaft 17 and in turn to the crank shaft (not shown) of the motor of which it forms a continuation. Thus the motor 14 will be rocked from the bearings supporting it, it being noted however that this rocking will occur to but a limited extent.

Further it will be understood that due to the peculiar construction of the bearings, that the same will at all times efliciently support the motor and immediately take up any wear which might occur at these points of su port.

hus it will be understood that all of the objects set forth in the preamble of this specification have been accomplished in that a direct drive is provided between the rear axle and the motor, and it will hence be unnecessary to utilize universal joints, and for this reason the loss of power heretofore occurring incident to the use of these members Wlll be avoided.

Obviously numerous modifications structure might readily be resorted to without in the least departing from the scope of my claims, which are:

1. A motor mounting including a chassis, bearings secured to said chassis, and upon each side thereof, brackets attached to said motor and trunnions forming continuations of said brackets and being engaged by said bearings, each of said bearings including a plurality of parts movable with respect to each other and longitudinal of the frame.

2. A motor mountin including a chassis, bearings secured to said chassis and upon each side thereof, brackets attached ,to said motor, and trunnions forming continuations of said brackets and being engaged by said bearings, said bearings including a plurality of parts movable longitudinal of the frame and means for pressing said parts into intimate engagement with said trunnions.

3. A motor mounting including a chassis, bearings secured to said chassis, brackets attached to said motor and trunnions forming continuations of said brackets and being engaged by said bearings, said bearings including a plurality of parts one of said parts being fixedly attached to said chassis, the second of said parts being slidably attached thereto, and means cooperating with the sec- 0nd of the bearing parts for pressing the same into engagement with said trunnions.

4. A motor mounting including a chassis, bearings secured toi siild chassis, brackets attached to said motor and trunnions forming continuations of said'brackets and being engaged by said bearings, said bearings in- 'cluding a plurality of parts one of said parts being fixedly attached to said chassis, the second of said parts being slidably attached thereto, said second bearing part being formed with a slot, a pin secured to said chassis and extending through said slot, and a spring having. one of its ends attached to said chassis, its opposite end bearing against the second part of said bearing.
